Amsterdam edged ahead of London to become Europe's biggest share trading centre in January, benefiting from Brexit forcing European Union investors to use platforms inside the bloc.
Exchanges in the Dutch capital traded €9.2 billion a day in January, more than London's €8.6 billion, according to figures from Cboe Europe exchange, which operates in both cities.
This compares with an average of €17.5 billion traded daily in London during 2020, when Frankfurt was second with €5.9 billion a day, and Amsterdam sixth at €2.6 billion daily, Cboe said.
However, trading in Swiss shares resumed in Britain this month.
It is averaging €250m a day and is expected to build up towards over €1 billion daily - the level before trading of Swiss shares in London stopped in June 2019.
The rise of Amsterdam was well flagged as pan-European share platforms Cboe and London Stock Exchange's Turquoise in London began preparations for opening hubs in the Dutch capital after Britain voted in 2016 to leave the EU.
Over €6 billion in daily trading left London on January 4 for EU-based platforms such as Cboe and Turquoise, but also increasing trading on national exchanges.
Brussels had been clear it wanted euro-denominated financial activity shifted from London to build up its own capital market and have direct supervision.
Some derivatives trading has also moved from London to Amsterdam and ICE exchange announced this week that trading in EU carbon emissions will move from London to the Dutch city later this year.
